Spokeswoman Michelle Michael told The Frederick News-Post Monday she doesn’t yet know how many of the 1,100 Frederick-based jobs will be moved.

She says the shift reflects a reorganization of the San Francisco-based contracting giant, starting Jan. 1. She says the jobs will be moved in phases.

Bechtel opened its Frederick operations in 1999. Those jobs are in the company’s power unit, which includes power plants and renewable energy. Bechtel announced last week that most of the power unit will be combined with the civil engineering division.

The reorganization also will create a global unit for nuclear power, environmental cleanups and facility security for defense departments in the United State and abroad.
